Finally the long-awaited CAPRISTOŽ valve exhaust system for the Corvette is here!! It fits both Corvette Z06 and ZR1 (all models).

This particular package was put together for vehicles that do not have the NNP option and it includes the Programmable Remote Control Kit. If your vehicle has the NNP option, then CLICK HERE to order the exhaust system WITHOUT the remote package.

This exhaust is a valve exhaust system, meaning it has two passages, or modes, that the exhaust can travel through the muffler. One side of the muffler is the "quiet" side, and one side is the "loud" side. The "quiet" side is a smaller, muffled and chambered tube, while the "loud" side is 4" (100mm) tubing straight through.

Each of the mufflers has two outlets, with one side having a butterfly type valve which allows the exhaust flow to be shut off, regulating which side of the muffler the flows exhaust.

The butterfly is controlled by a vacuum valve, which we built and developed completely by CAPRISTOŽ.

On the Z06 and the 2008 C6 with the NPP option, this valve is controlled by the onboard ECU. The valve opens based on RPM and throttle position.

The problem is that the factory OEM exhaust is very quiet, even with the valve open. Our expertise here at CAPRISTOŽ is getting the "tone" right for your Corvette, and we think we nailed this one.

Even in the closed position, the tone is deeper, louder, and more aggressive. Open the valves, the overall volume and tone increases to the point heads will turn when you drive up.

Not everybody has a Z06 or the 2008 with NPP, right? CAPRISTO Exhaust developed that system with that in mind. With the onboard Programmable Remote Control Kit, you will be able to take full advantage of this valve exhaust system system. The kit come complete with all the wiring, wireless remote control, vacuum line, vacuum accumalter, and vacuum switch needed for installation.

We have used the engine as the vacuum source (it is the same port the factory uses for the NPP) and the installation is simple and straight forward.

No welding needed. Includes all hardware and complete mounting instructions.
